We see one half of a desperate video phone call in this five-minute horror film, as a priest attempts to exorcise a man's demon with the help of a cell phone camera and the possessed man's young daughter. But can this long-distance exorcism succeed?

La Boca del León (The Lion's Mouth) was directed by Alfonso Garcia and received a special mention at the 2013 Sitges Film Festival for the best film recorded on a mobile phone. And it makes great use of its cell phone camera to capture all the intense moments of the attempted exorcism, even as we never see the frantic priest on the other end of the call.
